#     "Source" form shall mean the preferred form for making modifications,
#     including but not limited to software source code, documentation
#     source, and configuration files.

#     "Object" form shall mean any form resulting from mechanical
#     transformation or translation of a Source form, including but
#     not limited to compiled object code, generated documentation,
#     and conversions to other media types.

#     "Work" shall mean the work of authorship, whether in Source or
#     Object form, made available under the License, as indicated by a
#     copyright notice that is included in or attached to the work
#     (an example is provided in the Appendix below).

#     "Derivative Works" shall mean any work, whether in Source or Object
#     form, that is based on (or derived from) the Work and for which the
#     editorial revisions, annotations, elaborations, or other modifications
#     represent, as a whole, an original work of authorship. For the purposes
#     of this License, Derivative Works shall not include works that remain
#     separable from, or merely link (or bind by name) to the interfaces of,
#     the Work and Derivative Works thereof.

#     "Contribution" shall mean any work of authorship, including
#     the original version of the Work and any modifications or additions
#     to that Work or Derivative Works thereof, that is intentionally
#     submitted to Licensor for inclusion in the Work by the copyright owner
#     or by an individual or Legal Entity authorized to submit on behalf of
#     the copyright owner. For the purposes of this definition, "submitted"
#     means any form of electronic, verbal, or written communication sent
#     to the Licensor or its representatives, including but not limited to
#     communication on electronic mailing lists, source code control systems,
#     and issue tracking systems that are managed by, or on behalf of, the
#     Licensor for the purpose of discussing and improving the Work, but
#     excluding communication that is conspicuously marked or otherwise
#     designated in writing by the copyright owner as "Not a Contribution."

#     "Contributor" shall mean Licensor and any individual or Legal Entity
#     on behalf of whom a Contribution has been received by Licensor and
#     subsequently incorporated within the Work.

#  2. Grant of Copyright License. Subject to the terms and conditions of
#     this License, each Contributor hereby grants to You a perpetual,
#     worldwide, non-exclusive, no-charge, royalty-free, irrevocable
#     copyright license to reproduce, prepare Derivative Works of,
#     publicly display, publicly perform, sublicense, and distribute the
#     Work and such Derivative Works in Source or Object form.

#  3. Grant of Patent License. Subject to the terms and conditions of
#     this License, each Contributor hereby grants to You a perpetual,
#     worldwide, non-exclusive, no-charge, royalty-free, irrevocable
#     (except as stated in this section) patent license to make, have made,
#     use, offer to sell, sell, import, and otherwise transfer the Work,
#     where such license applies only to those patent claims licensable
#     by such Contributor that are necessarily infringed by their
#     Contribution(s) alone or by combination of their Contribution(s)
#     with the Work to which such Contribution(s) was submitted. If You
#     institute patent litigation against any entity (including a
#     cross-claim or counterclaim in a lawsuit) alleging that the Work
#     or a Contribution incorporated within the Work constitutes direct
#     or contributory patent infringement, then any patent licenses
#     granted to You under this License for that Work shall terminate
#     as of the date such litigation is filed.

#  4. Redistribution. You may reproduce and distribute copies of the
#     Work or Derivative Works thereof in any medium, with or without
#     modifications, and in Source or Object form, provided that You
#     meet the following conditions:

#     (a) You must give any other recipients of the Work or
#         Derivative Works a copy of this License; and

#     (b) You must cause any modified files to carry prominent notices
#         stating that You changed the files; and

#     (c) You must retain, in the Source form of any Derivative Works
#         that You distribute, all copyright, patent, trademark, and
#         attribution notices from the Source form of the Work,
#         excluding those notices that do not pertain to any part of
#         the Derivative Works; and

#     (d) If the Work includes a "NOTICE" text file as part of its
#         distribution, then any Derivative Works that You distribute must
#         include a readable copy of the attribution notices contained
#         within such NOTICE file, excluding those notices that do not
#         pertain to any part of the Derivative Works, in at least one
#         of the following places: within a NOTICE text file distributed
#         as part of the Derivative Works; within the Source form or
#         documentation, if provided along with the Derivative Works; or,
#         within a display generated by the Derivative Works, if and
#         wherever such third-party notices normally appear. The contents
#         of the NOTICE file are for informational purposes only and
#         do not modify the License. You may add Your own attribution
#         notices within Derivative Works that You distribute, alongside
#         or as an addendum to the NOTICE text from the Work, provided
#         that such additional attribution notices cannot be construed
#         as modifying the License.

#     You may add Your own copyright statement to Your modifications and
#     may provide additional or different license terms and conditions
#     for use, reproduction, or distribution of Your modifications, or
#     for any such Derivative Works as a whole, provided Your use,
#     reproduction, and distribution of the Work otherwise complies with
#     the conditions stated in this License.

#  5. Submission of Contributions. Unless You explicitly state otherwise,
#     any Contribution intentionally submitted for inclusion in the Work
#     by You to the Licensor shall be under the terms and conditions of
#     this License, without any additional terms or conditions.
#     Notwithstanding the above, nothing herein shall supersede or modify
#     the terms of any separate license agreement you may have executed
#     with Licensor regarding such Contributions.

#  6. Trademarks. This License does not grant permission to use the trade
#     names, trademarks, service marks, or product names of the Licensor,
#     except as required for reasonable and customary use in describing the
#     origin of the Work and reproducing the content of the NOTICE file.

#  7. Disclaimer of Warranty. Unless required by applicable law or
#     agreed to in writing, Licensor provides the Work (and each
#     Contributor provides its Contributions) on an "AS IS" BASIS,
#     WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
#     implied, including, without limitation, any warranties or conditions
#     of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
#     PARTICULAR PURPOSE. You are solely responsible for determining the
#     appropriateness of using or redistributing the Work and assume any
#     risks associated with Your exercise of permissions under this License.

#  8. Limitation of Liability. In no event and under no legal theory,
#     whether in tort (including negligence), contract, or otherwise,
#     unless required by applicable law (such as deliberate and grossly
#     negligent acts) or agreed to in writing, shall any Contributor be
#     liable to You for damages, including any direct, indirect, special,
#     incidental, or consequential damages of any character arising as a
#     result of this License or out of the use or inability to use the
#     Work (including but not limited to damages for loss of goodwill,
#     work stoppage, computer failure or malfunction, or any and all
#     other commercial damages or losses), even if such Contributor
#     has been advised of the possibility of such damages.

#  9. Accepting Warranty or Additional Liability. While redistributing
#     the Work or Derivative Works thereof, You may choose to offer,
#     and charge a fee for, acceptance of support, warranty, indemnity,
#     or other liability obligations and/or rights consistent with this
#     License. However, in accepting such obligations, You may act only
#     on Your own behalf and on Your sole responsibility, not on behalf
#     of any other Contributor, and only if You agree to indemnify,
#     defend, and hold each Contributor harmless for any liability
#     incurred by, or claims asserted against, such Contributor by reason
#     of your accepting any such warranty or additional liability.
